Summary
ManageEngine Log360 Builds < 5235 are affected by an improper access control vulnerability allowing database configuration overwrite. An unauthenticated remote attacker can send a specially crafted message to Log360 to change its backend database to an attacker-controlled database and to force Log360 to restart. An attacker can leverage this vulnerability to achieve remote code execution by replacing files executed by Log360 on startup.
Exploit prediction
10.79% chance of exploitation in the next 30 days, higher than 95% of all scored CVEs (FIRST EPSS, 2026-11-08).
